As of July 2010 you can only use the trailed builds with the e3000 name in it for initial flashing and nothing else, using other bin's without the e3000 name in it for initial flashing may result in a bricked unit! After you have dd-wrt installed to your unit, you can then use the e2k-e3k.bin's for upgrading to newer builds.

DD-WRT E3000 Build information

Always use the E~ series builds for upgrading. Anything else will brick your unit

The latest builds for this unit can be currently found in the FTP. Support was added in 14826 and on.

Also it has been asked about the builds with e2k-e3k name in them, these builds are for if you already have those units flashed with dd-wrt, you can simply use one of those builds to upgrade, but the initial flash should always be done with the trailed build (build with the unit only name in it) linked above.

At step 5: "Wait 5 minutes until WAN light turns on". I waited for 5 minutes but the WAN light never turned on (I had no ethernet cable connected to the wan port). I didn't bother to wait for the WAN light to come up but I did wait the 5 minutes to continue with step 6 and further.

The steps above also apply for people running a converted E3000 with a stock linksys firmware. With these steps it is possible to flash your converted E3000 (running stock linksys firmware) with DD-WRT.
